States, residin at One object of the invention is to provide a practical and eilicient sanding de-4 vice of the character described which shall positivel function to reduce to a minimum the skid ing of motor vehicles.

Another object of the invention is to provide a sanding device of the character described which shall be simple and easy in operation and readily attachable to an automobile.

A further object is to provide a sanding device of the character described with means for keeping the sand dry and warm and preventing same from congealing or solidilying.

@ther objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists 1n the features of construction, combinations o elements and arrangement of parts which will be exemplified in the construction hereinafter described and of which the scopo of 'application will be indicated inthe following claims. i

ln the accompanying drawings, in which is shown one of various possible illustrative embodiment of this invention,

Fig. 1 is a partial side elevational view of a touring car partly in cross-section provided With a sanding device embodying this invention;

Fig. 2 is thereof;

Fig. 3 is an enlarged detailed cross-sectional view of the sand box taken along line 3--3 of Fig. 1; and

Fig. 4 is a partial perspective view showing an embodiment of the invention in place on the frame of' an automobile truck.

Referring in detail tothe drawing, in Figs. 1, 2 and 3, my invention is illustrated as applied 'to a touring car of any wellknown construction. In these gures 10 indicates the car body of. rlhe sanding device comprises a sand a diagrammatic partial plan view EDWARD Hinson, a,

f rod 23 adjacent and 11 the floor therebox or hopper 13 suitably secured underneath the car body and made of any suitable material, preferably sheet metal. make theA sand box` preferably of double walled construction so as to enclose an air space la between the inner wall 15 and the outer wall 16 of the box, for the purpose hereinafter described. Extending from the hopper is a spout or outlet tube 17 bent toward the rear Wheel 18 of the car so that the sand when released from the hopper will be deposited directly in front of said wheel. The delive is controlle by means of a valve or door 19 operated by a suitable lever arrangement adapted to be actuated by the driver. ln the form shown in the drawing, a hand lever 20 is arranged in front of the drivers seat adjacent the. steering wheel 21. Connected to the lower end of said hand lever as at 22 is a longitudinal rod'23, the other end 24 of which is connected as at 25 to a lever 26a pivoted on the cross shaft 27. A similar lever 26b is pivoted to the same shaft 27 and has connected thereto another longitudinal rod 28, the forward end oi' which is pivotall connected as at 29 to the link 30 to w ich the valve 19 is operatively secured as at 31. Mounted on the the rear end thereof is a coil spring 32 held between a collar 33 and a bracket 34 arran ed in spaced relation on said rod. lf desired, the hand lever 20 may be provided with a projection 20a adapted to enter in a corresponding notch 35a of a segment 36 and to be held in place by means of a locking rod 20 when the hand lever is thrown forwar lf desired, one sand box such as described may be provided for each of the rear wheels of the car as shown in Fig. 2 and operated from the same hand lever and link mechanism, the cross shaft 27 extending clear across the automobile chassis for connection as at 37 with the link 38 connected to the valve or door of the other sand box 39. ln'this way, the operation of the hand lever 20 will simultaneously open or close the valves in each of the sand boxes 13 and 39.

VDiiliculty has been experienced with sanding devices of this character in that the sand very'often freezes in cold weather or becomes lumpy due to dampness. My invention includes means for constantly heating'the sand in the sand box so as to prevent lcongelation or solidiication of the of the sand from the hopper sand. To accomplish this end in a cheap and eficient manner, l preferably employ the heat of the exhaust gases. lin the form shown in the drawing, l provide on the exhaust outlet 40 an air chamber 41 which surrounds the exhaust outlet and communicates with 'the air space 14 by means of a connecting tube 42. The air chamber 41 is provided with perforations 41 through whlch air enters from the outside. Perforations 13' are likewise provided adjacent to top of the hopper 13, communicating with the air space 14, thus making this air space open to the outside. The air in the chamber is subjected tothe heat of the exhaust gases issuing from the exhaust manifold 43 through the exhaust outlet 40. ln this way the air in the airspace 14 surrounding the sand 44 in the sand box is kept warm. and the sand consequently kept suiiiciently dry so as to be always available and flow freely from the spout 17. To further insure the maintaining of the sand at a proper temperature, ll provide on the outside of the hopper a covering of asbestos or the like heat insulatin material 45.

lln Fig. 4 have shown an embodiment of the invention as applied to an automobilel truck. ln this form the sand box is mount-- ed on a platform 45 which is suspended from the side frame 46 of the truck by means of straps 47 suitably fastened or riveted to the frame. linasmuch as in this construction the sand box is exposed, ll preferabl enclose the same in a rectangular box 48 liaving a lid 49 which may be locked by a pad-lock 50. 4

ln the form shown in Figs. 1, 2 and 3, the hopper is located preferablyunderneath the floor of the touring car adjacent the rear seat, the floor being cut out as at 51 to provide a shoulder 52 on which rests corresponding flanged portions 53, 54 of the interior and exterior walls of the hopper. A cover 55 is provided so as to be flush with the floor and to be lifted or slid o' when access is desired to the hopper. Preferably ll provide a sieve member 56 at the top of the hopper so that any foreign material such as lpebbles and the like may be sifted out from the sand as it is per. The cover 56 is preferably spaced from the hopper by means of a thin washer or layer of material 57.

The operation of the device will be clear. When the vehicle is moving on wet ground, or at the time of emergency the driver throws the hand lever 20 forward thus opening the valve 19 through the link and lever mechanism described. ln this operation the rod 23 moves rearward land collar 33 thereon compresses the spring 32 against the bracket 34. llf the operator desires the sand to be. supplied in front of the rear wheels continuously for a period of time, the

placed in the hopnavegas of the projection 20n in lt will thus be seen that there is provided l a device in which the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various ossible embodiments might he made of the a ove invention and as various changes might be madein the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
